The system uses five agents with distinct roles and system prompts, passing outputs sequentially. The implementation is simpler, more debuggable, and works with any LLM provider.", "body_md": "You dont need CrewAI or AutoGen. Heres how to build a multi-agent pipeline in pure Python.\n\n##\nThe Concept\n\n5 AI agents collaborate in a pipeline:\n\nEach agent has a role, a system prompt, and passes output to the next.\n\n##\nImplementation\n\n##\nWhy No Framework?\n\n-\n**Simpler**: 50 lines vs 500 lines with CrewAI\n-\n**Debuggable**: You can see exactly whats happening\n-\n**Flexible**: Add/remove agents easily\n-\n**No dependencies**: Just `requests`\n\nlibrary\n-\n**Works with any LLM**: Ollama, OpenAI, Groq, anything\n\n##\nPro Tips\n\n-\n**Different models per agent**: Use codellama for code review, llama3.2 for writing\n-\n**Temperature**: Lower for Researcher (factual), higher for Writer (creative)\n-\n**Fallback**: If one model fails, try another\n-\n**Logging**: Save each agents output for debugging\n\n##\nUse Cases\n\n- Blog post pipeline\n- Video script generation\n- Social media content\n- Research reports\n- Code review chains\n\n🔗 Full implementation: [github.com/amrendramishra/ai-tools](https://github.com/amrendramishra/ai-tools)\n\n🌐 [amrendranmishra.dev](https://amrendranmishra.dev)\n\n*Building AI tools daily.
